The mouse inoculation test in rabies diagnosis: early diagnosis in mice during the incubation period
Abstract:
Brain tissue from 64 rabies suspect specimens were inoculated intracerebrally into twenty 9-12 gm adult Swiss white mice. Two mice from each specimen were killed on specific days postinoculation and examined for the presence of rabies virus by the fluorescent antibody staining technique. In this way a positive diagnosis was made in the majority of cases between postinoculation days 4 and 12 when the incubation period of these same specimens ranged between eight and 20 days.
Insights
This study used mice to detect rabies virus in suspect specimens. A positive diagnosis was achieved between 4 and 12 days post-inoculation, correlating with incubation periods of 8-20 days.
Area of Science:
- Veterinary Pathology
- Virology
- Diagnostic Microbiology
Background:
- Rabies virus poses a significant threat to public health and animal populations worldwide.
- Accurate and timely diagnosis of rabies is crucial for disease control and prevention.
Purpose of the Study:
- To evaluate the efficacy of intracerebral inoculation in mice combined with fluorescent antibody staining for rabies virus detection.
- To determine the optimal time frame for diagnosis post-inoculation.
Main Methods:
- Brain tissue from 64 suspect rabies specimens were inoculated intracerebrally into adult Swiss white mice.
- Two mice per specimen were examined using the fluorescent antibody staining technique on specific post-inoculation days.
Main Results:
- A positive diagnosis for rabies virus was achieved in the majority of cases between post-inoculation days 4 and 12.
- The observed diagnostic window correlated with specimen incubation periods ranging from 8 to 20 days.
Conclusions:
- Intracerebral inoculation in mice followed by fluorescent antibody staining is an effective method for rabies virus diagnosis.
- Early detection of rabies virus is feasible within a 4-12 day post-inoculation period.
